GAS-CONDENSER.

Specification of Letters Patent.

Application filed September 7, 1912. Serial No. 719,048. 7

To all whom, it may concern:

Be it known that I, COMMODORE R. MILLER, a citizen of the United States, and residing in the borough of \Voodlawn, in the county of Beaver and State of Pennsylvania, have invented or discovered new and useful Improvements in Gas-Condensers, of which the following is a specification.

My invention consists in a new and improved condenser for gas.

The gas passes from the producer in a highly heated and expanded state, holding in suspension impurities or uncombined substances such as coal-tar, water-vapor, etc. To fit the gas for use it is necessary to condense it and remove the impurities.

My condenser provides a tortuous gas-passage whose outer surface is air and Water cooled and over which are caused to flow continuous currents of cold water. Means are also provided for precipitating and drawing off the impurities.

My apparatus is inexpensive of construction and operation, occupying but little space and efiectively condensing and purifying the gas treated therein.

Many novel features of structure and arrangement of parts will appear fro-m the following description.

In the accompanying drawings, Figure 1 is a side elevation of my condenser, the

stand-pipes and base being shown in Vertical section for the sake of clearness, and Fig. 2 is a plan view of the same, the stand-pipes and gas-pipes being shown in horizontal section.

The following is a detailed description of the drawings:

A is an inclosed metal base or box rovided along one side with tightly fitting cleaning doors 11.

2 is a valved discharge pipe leading from the base A intermediate of its height and emptying into a water-seal 8. The base Ais charged with water up to the level of pipe 2 and the valve in pipe 2 is normally open.

The top of base A is provided with a continuous vertical edge-flange A, forming an open reservoir from which leads an overflow discharge pipe 5. The top of base A is also provided with a longitudinal row of circular ports, such as 6, 6, 6*, 6, 6 and 6 Between the ports 6" and 6 in the interior of base A is a depending bafile 7 whose lower extremity is below the level of the water in,

base A. A similar bafiie, '7 is located between the ports 6 and 6 B is a gas-pipe leading from the producer orother source of supply, not shown, and communicating with the port 6.

C is a substantially inverted U-shaped gas-pipe mounted'on base A and having its legs communicating with the ports 6 and 6". A similar pipe D connects ports 6 and 6 E is a pipe communicating with port 6 and connected with the gasometer or pipeline, not shown.

Gaskets 88 are interposed between the flanged bases of pipes B, C, D and E and the top of base A to obtain gas-tight joints. The gas-pipes C and D are provided with capped hand-holes 99 for cleaning purposes.

FF are vertical stand-pipes of greater diameter than gas-pipes O, D and E and concentric therewith, the bases of said standpipes being mounted on and secured by water-tight joints to the base-flanges of said gas-pipes. The tops of pipes F-F are open and their bases are connected to a water supply pipe G by branch pipes 1010.

The operation of my invention is as follows: The gas entering through pipe B is deflected up into pipe C by baflie 7 passing through said pipe G into base A in the rear of baflie 7. It is thence deflected by bafiie '7 into pipe D and passing through said pipe D enters the base A in the rear of baflie 7 a and escapes from the condenser through the pipe E. The water admitted to stand-pipes F-F through pipes 1010, fills said standpipes surrounding the vertical portions of pipes C, D and E with a constantly renewed supply of cold water. As the water flows over the tops of pipes FF and runs down the exterior surfaces thereof in a sheet, it becomes aerated and recooled and falls into the reservoir formed by the flange 4; chilling the base A and the excess escaping by pipe 5. The supply of Water through pipes 1010 is constant while the condenser is in use so that there is a continuous flow of cold water over the gas conductors. The result of the exposure of the gas to this cooling effect and its tortuous course through the cooler is its condensation and the precipitation of the impurities, which latter are deposited in the Water contained in the base A Patented Aug. 26,1913.

and float oil through the pipe 2, the escape of gas being prevented by water-seal. 3. The base A may be cleaned, when required, through the doors 11.

WVhat I desire to claim is 1. In a gas-condenser, a box formed with a bottom, sides and top, a continuous vertical edge flange projecting upward from the box-cover and forming an open-topped reservoir directly above said box-top, a discharge-pipe leading from said reservoir, U- shaped pipes communicating with the interior of said box through said boxtop, open-topped stand-pipes surrounding the vertical portions of said U-shaped pipes, and means for supplying a cooling liquid, under pressure, to the base of said standpipes, causing the "liquid to flow down over the exterior wall thereof, the cold water sinking to the bottom of said reservoir and the warm water in said reservoir rising to the top and escaping through said dischargepipe; whereby the said reservoir and, consequently, the interior of said box are maintained constantly chilled.

2. In a gas-condenser, a box formed with a bottom, sides and top, a continuous vertical edge flange projecting upward from the box-cover and forming an open-topped reservoir directly above said box-top, a discharge-pipe leading from said reservoir, baffles disposed in said box, U-shaped pipes communicating with the interior of said box through said box-top, open-topped standpipes surrounding the vertical portions of said U-shaped pipes, and means for supplying a cooling liquid, under pressure, to the base of said stand-pipes, causing the liquid to flow down over the exterior wall thereof, the cold water sinking to the bottom of said reservoir and the warm water in said reservoir rising to the top and escaping through said discharge-pipe; whereby the said reservoir, and, consequently, the interior of said box are maintained constantly chilled.

Signed at Pittsburgh, Penna, this 10th day of June, 1912.
